PDF Compression

A PDF is a type of document file. It is very similar to the DOC format in that they both contain textlinksand even images.

Howeverunlike DOC filesPDF files are more like a snapshot of an existing document. This makes them very versatile because they look the same across various systems. This means you can create a PDF on a macOS computer and it will look exactly the same on a Windows computer. In factit will also look the same on your smartphone or even your TV. DOCs don't have this versatility.

HoweverDOC files are usually pretty small when it comes to file size because they pull information from the system on which they are openedsuch as installed fontsfor example. PDFson the other handcan get quite largeespecially if there are many images inside.

Why would you need to compress PDFs?

Since PDFs can get pretty heavy in sizeyou might face limitations with sharing them. For exampleif you have a PDF that's larger than 50MByou might not be able to upload it to certain websites. You might even have trouble emailing itdepending on which email service you use.

Compression is a way to make an existing PDF smaller. With PDF compressionyou can optimize your document(s) so they are easier to share and take up less space on your hard drive. In some casesthis can literally halve the size of a PDF!
